Agree - it's very difficult to swing the statistics to argue from a factual - rather than emotional standpoint that access to firearms makes you safer. An increase in firearm ownership significantly correlates with a increase in gun related deaths, even with the US excluded. http://mark.reid.name/iem/gun-deaths-vs-gun-ownership.htmlI'd feel more threatened in an environment where guns are easily accessed, increasing the chance that one will be accessed by a person that has a desire to kill for the sake of killing.
Increased gun ownership correlates with a higher rate of gun related homicide, but not having a gun does not correlate with non-firearm homicide rate:
"Using survey data on rates of household gun ownership, we examined the association between gun availability and homicide across states, 2001-2003. We found that states with higher levels of household gun ownership had higher rates of firearm homicide and overall homicide. This relationship held for both genders and all age groups, after accounting for rates of aggravated assault, robbery, unemployment, urbanization, alcohol consumption, and resource deprivation (e.g., poverty). There was no association between gun prevalence and non-firearm homicide."

Being in possession of gun when you are assaulted significantly increases the likelihood you will be shot during that assault.
"...After adjustment, individuals in possession of a gun were 4.46 (P < .05) times more likely to be shot in an assault than those not in possession. Among gun assaults where the victim had at least some chance to resist, this adjusted odds ratio increased to 5.45 (P < .05)."

Second, is the extremely low probability that you will be murdered by a complete stranger (e.g. http://malini.data360.org/graph_group.aspx?Graph_Group_Id=1177; http://www.heraldscotland.com/news/crime-courts/stranger-murder-myth-dispelled.19350541). Violent crime is not generally random, and the risk posed by random violent attacks is extremely disproportionate to the risks involved in having a loaded weapon in your house for self defense - a gun in your house is around 22 times more likely to be used on an occupant than to be used in self defense http://journals.lww.com/jtrauma/Abs..._Deaths_Due_to_Firearms_in_the_Home.10.a spx
The real argument in the US is given the validated right of a person to own a gun for the purpose of defending oneself (a right NOT mandated in Australia or Switzerland), what is the appropriate trade off between one person's second amendment right to bear arms, and another person's constitutional right to "life and liberty"? Clearly gun ownership has a negative impact on life and liberty at large, clearly gun control has an impact on the rights of the individual. Having lived in both places, I think Australia has the trade off a lot better worked out than the US.
